Kendo UI Default Grid Filter value

I am trying to default a Kendo UI grid to be filtered on page load. I have a column with boolean values that I need to only display the ones with "false" on page load but allow the user to see them all if they clear filters.

Example: http://www.telerik.com/forums/adding-filters-to-grid-s-source

    function updateSearchFilters(grid, field, operator, value) {
        var newFilter = { field: field, operator: operator, value: value };
        var dataSource = grid.data("kendoGrid").dataSource;
        var filters = null;
        if ( dataSource.filter() != null){
            filters = dataSource.filter().filters;
        }       
        if ( filters == null ) {
            filters = [newFilter];
        }
        else {
            var isNew = true;
            var index = 0;
            for(index=0; index < filters.length; index++) {
                if (filters[index].field == field) {
                    isNew = false;
                    break;
                }
            }
            if ( isNew){
                filters.push(newFilter);
            }
            else {
                filters[index] = newFilter;
            }
        }
        dataSource.filter(filters);
    }

I have tried this solution to call a function on the DataBound event but when the user clears the filter and then tries to group or set other filters, this filter reappears. I am using Razor syntax in the view and was hoping there would be something to set there.

Update: For the time being, I have wrapped the example function in an if on a class level variable that is set to true/false based on if it has been called before but I feel like this is a primitive solution.

    function onDataBind(grid, field, operator, value){
        if(!alreadyFiltered) //class level variable that is set to true after dataSource.filter(filters);
            updateSearchFilters(grid, field, operator, value);
        }
    }
